Oil-water separation type aircraft oil supply tank provided with oil level control system

Abstract

The invention discloses an oil-water separation type aircraft oil supply tank provided with an oil level control system, and relates to the technical field of aerospace equipment. The aircraft oil supply tank comprises a shell; an oil level control device is arranged in a cavity of the shell; an oil outlet pipe joint is arranged at the right end of an oil outlet pipe, and an oil drain valve switchis arranged at the end opening of the oil outlet pipe joint; an oil filter installation hole is formed in a bottom plate of the shell; an end cover is arranged in the middle of the lower end of the outer wall of the shell, the end cover is fixed to the bottom of the shell through bolts, a seal gasket is arranged between the shell and the end cover, and a sediment discharge switch is arranged in the middle of the end cover; an oil filter tank is arranged in the middle of the bottom end of the inner wall of the shell, and the oil outlet pipe is arranged at the lower end of the right side of theoil filter tank. By means the oil-water separation type aircraft oil supply tank provided with the oil level control system, the purposes of oil-water separation, oil level control and high sealing of the oil drain valve switch are achieved, and the maintainability and safety of an aircraft are greatly improved.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to an oil-water separation type aircraft fuel supply tank equipped with an oil level control system. Background technique [0002] The performance of the fuel filter is generally matched according to the engine's requirements for fuel filter accuracy and the physical properties of the working medium. According to aircraft airworthiness or military standard requirements, two types of oil filters are generally installed in the aircraft fuel supply system, one is coarse oil filter and the other is essential oil filter. The coarse oil filter is usually installed at the inlet of the engine oil supply pipeline in the fuel supply tank to initially filter the large impurities in the fuel to prevent the essential oil filter from being blocked quickly; the essential oil filter is generally installed on the engine oil supply pipeline outside the fuel supply tank In the process, th...
